View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.LESCALLOY 4335+V VAC-ARC is a low-alloy steel with high hardenability and good strength and toughness. It is produced by the vacuum consumable electrode melting process to provide optimum cleanliness and preferred ingot structure. Its uses include aircraft and aerospace components, gears, shafting, bolts and crankshafts.
